ROLLER CONSTRUCTION.

Application filed July 26, 1919.

To all whom it may concern Be it known that I, Doucnas TURNER, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented new and useful Improvements in Roller Construction, of which the following is a specification.

This invention relates to a roller construction and especially to the parts by means of which the roller is rotatably mounted. "Vhile certain features of the invention may be used in machines of any kind, the invention has special features adapting it to be particularly useful in constructing and mounting the measuring rollers of fabric measuring and cost computing machines. In machines of this kind a presser roller cooperates with the measuring roller to hold the fabric against the surface and when the fabric is pulled through the machine, the rotation of the measuring roller is imparted to the indicating mechanism, which indicates the length of the piece of oods measured or the cost of the same. onsiderable difliculty has been encountered in the construction and mounting of these rollers, by reason of the fact that small pieces of lint tend to accumulate in the bearings of the roller, which clogs the bearings and decreases the etliciency of the measuring roller as a driving means for the indicating mechanism.

The general object of the present invention is to produce a very simple roller construction which will operate as a good bearing support for a roller used for any purpose whatever. As applied to the type of machine described above, one of the objects of the invention is to provide a roller construction which not only affords a good bearing support for the roller, but which is also constructed in such a way as to prevent the accumulation of lint in the bearing.

Further objects of the invention will appear hereinafter.

The invention consists in the novel features, and in the general combination of parts to be particularly described hereinafteigall of which contribute toproduce a simple and efficient roller construction. A preferred embodiment of my invention will be particularly described in the following specification, while the broad scope of my invention will be pointed out in the appended claims.

, Specification of Letters Patent.

Patented Sept. 13, 1921.,

Serial No. 313,658.

In the drawing- Figure 1, is a longitudinal section through a roller construction embodying my invention.

2, is a partial elevation, and partial section taken about the location of the line 22 of .Fig. 1.

In practising my invention, I provide a substantially cylindrical shell 1, which is preferably provided at its middle point with a transverse head 2. This roller is rotatably supported by fixed means disposed at each end of the roller. When the roller construction is to be used in a machine of the type referred to, the fixed supporting means preferably consists of a fixed arbor 3 which extends co-axially with the roller. at one end, and a second arbor 4 which also extends co-axially with respect to the roller, at the outer end of the roller. In the present instance, these arbors 3 and 4 are of tubular or sleeve form, and their inner ends are enlarged to form collars 5 which operate as lint-guard collars for the roller, the collars being received in counterbores 6 for this purpose formed in the faces of the transverse head 2.

The collars 5 are preferably countersunk to fit neatly into counterbores 6; the head 2, located as it is, at a considerable distance within the ends of the roller results in forming a deep pocket 7 in each end of the collar.

The fixed arbor 3 is preferably rigidly attached in an opening in a vertical frameplate 8, by means of a nut 9, which screws onto threads on the end of the arbor. The outer arbor 4: is supported on a fixed bracket or post 10, which, like the frame-plate 8, is

secured to a base-plate or base 11.

The s1mple construction described above constitutes a very effective roller construction. In assembling the parts, the arbor 3 is first put in place and then the roller is slipped over it, after which the post 10 carrying the outer arbor 4: is secured in place by attaching it to the base 11 by means of suitable screws, such as screw 12 (see Fig. 2). If desired, a shaft, such as the shaft 13, may be employed, which shaft is co-axial with the arbors, and this shaft may extend into both arbors, the middle portion of the shaft passing through the portion of the roller lying between the collars 5.

In the type of measuring machine referred to, I provide for driving the shaft by means of the measuring roller, and this is accomplished by attaching the shaft nonrotatably in the roller in any suitable manner, for example, by means of a key 14, extending from the shaft and received in a key way 15 formed in the head 2. The inner end of the shaft projects through the vertical frameplate 8, and it may be provided with any suitable means such as a pinion 16 to mesh with a train of gears for driving the indicating mechanism of the machine. In this way it is evident that the shaft will operate as a driving means for the indicating mechanism. It will be noted that the arbor 3 completely covers the shaft at the inner end of the roller, from the frame plate to the head, so that it is impossible for lint to work its way between the shaft and the arbor If desired, the shaft 13, can be made to fit in the tubular arbors as a journal, but I prefer to support the inner end of the shaft in a hearing or bushing 17 mounted in the inner end of the fixed arbor 3. The pinion 16 may be attached on a suitable hub or collar 18, rigidly attached to the projecting end of the shaft. At the outer end of the roller I provide means for covering the end of the shaft 13, so as to prevent any possibils ity of lint working its way between the shaft 13 and the outer arbor 4; for this purpose I provide fixed means in the form of a bushing 19, which forms a bearing for a reduced neck 20, formed on the end of the shaft. This bushing is mounted in the end of the arbor 4t and the bore through the bushing adjacent the outer face of the bushing is threaded to receive a removable screw 21. It is evident that this bushing and screw effectively cover the outer end of the shaft and hence, it will be seen that the shaft of the roller is very effectively covered up and concealed in such a way as to exclude lint. The only possible place that lint could find its way into the rollers bearings, is at the adjacent ends of the arbors but these are counter-sunk into the roller, preferably with the outer faces of the collars 5 flush with the end faces 22 of the head 2. These collars, located as they are, at the bottoms of the deep pockets 7 will not be reached by the lint if the pockets are cleaned from time to time. s

In order to enable the roller to perform its functions effectively as a measuring roller, the shell 1 is provided with a cover or clothing 23, of any suitable composition.

lVhen the machine is measuring, the fabric is pressed against the face of the measuring roller by a suitable presser roller in, dicated by the dotted outline 2 1 in Fig. 2.

It is understood that the embodiment of the invention described herein is only one of the many embodiments my invention may take, and I do not wish to be limited in the practice of my invention nor in my claims, to the particular embodiment set forth.

What I claim and desire to secure by Letters Patent is v 1. In a measuring roller construction for a fabric measuring and cost computing ma chine, the combination of a substantially cylindrical shell having a pocket extending into each end of the shell and having a transverse head between the pockets, a shaft received in the head and connected thereto so as to be rotated by the roller when it rotates, a fixed arbor extending axially into each end of the shell, completely covering the shaft within the pocket and in the vi cinity of the roller, said head having counterbores fitting to and receiving the ends of the arbors and cooperating with the arbors to exclude lint from contact with the shaft.

2. In a measuring roller construction for a fabric measuring and cost computing machine, the combination of a substantially cylindrical shell having a pocket extending into each end of the shell and having a transverse head between the pockets, a substantially vertical frameplate, a shaft received in the head, connected thereto so as to be rotated by the roller, and extending through the frame-plate, a fixed arbor supported by the frame-plate extending into the pocket in the adjacent end of the roller and completely covering the roller from the plate to the head, another fixed arbor extending axially into the pocket at the other end of the roller, said head having a counterbore on each side of the same fitting to and receiving the'ends ofsaid arbors respectively, and cooperating with the arbors to exclude lint from contact with the shaft.

3. In a measuring roller construction for a fabric measuring and cost computing machine, the combination of a substantially cylindrical shell having a pocket extending into each end of the shell and having a transverse head between the pockets, a substantially vertical frame plate, a shaft passing through the head and connected thereto so as to be rotated by the roller, and extending through the frame-plate, a fixed arbor supported by the frame-plate, extending into the pocket in the adjacent end of the roller and completely covering the shaft from the plate to the head, a fixed bracket adjacent to the outer end of the roller, a fixed arbor supported in the bracket extending axially into the pocket at the adjacent end of the roller, completely covering the shaft from the bracket to the head, said head having a counterbore on each side of the same fitting to and receiving the ends of said arbors respectively, and cooperating with the arbors to exclude lint from contact with the shaft, and means fixed in the outer end of the second named arbor for closing the same.

In testimony whereof, I have hereunto set my hand.
